Description

And display of the display

In particular, the present invention relates to the click light method of the display and its display, and particularly to the click light method of adjusting the degree of the click light and the display.

For example, in a device that is related to light, the device detects the surrounding arm with a front display or a sensor that is mounted around the cropping unit, and adjusts the front display's light level according to the detection. Take control (for example, 200 268220 ()).

If the measured value is relatively high (comparative), the degree of light is increased to secure, and conversely if the measured illuminance is relatively high (comparative), the climatic value is decreased. Decrease the crack rate because it will not damage the surface. As a result, it is possible to secure the power. In addition, the brightness is changed step by step to further reduce the sense of harmony with the degree of click light. In addition, when the fold-up state is changed from the closed state to the open state, the light changes from step to step based on the measured illuminance.

In addition, in the above-mentioned description, a technique is disclosed in which the light is gradually adjusted to a predetermined level after the light is once added. In addition, a position where an illuminance sensor is arranged on the side A is described in Japanese Patent No. 200404472 (2). Mysterious

Issues that Ming tries to solve When the connected folding device is in the open state from the closed state, the measured value immediately after opening is used in consideration of the light, but the measured value immediately after opening the In many cases, the value is too small even in relatively small environments.

Fig. 7 is a diagram showing an example of the change in the degree of click light when is changed from closed to open. In addition, the horizontal axis represents time, and the horizontal axis represents time. If the crease and illuminance measurement values of the connected folding devices are relatively low (comparative), 7 a will be shown in the connected device, and if the illuminance measurement value is relatively high) 7 b This is shown in the following figure.

Looking at the time required to ensure visibility in a comparative environment, the time is 3 when the illuminance measurement value is relatively low (in 7 7a), and the time when the illuminance measurement value is high (in 7-7b). ) Is time 2 (2 3). Therefore, when the illuminance measurement value is relatively high, the time required for securing it is much longer than when the illuminance measurement value is relatively high. For this reason, there is a problem that when a relatively environment is opened, there is a bad state.

On the other hand, although the technique disclosed in the patent discloses a technique for controlling the length of the clock according to the surroundings, the measured value immediately after opening is not fully considered. Therefore, the purpose of this is a clear statement of the purpose and the whole, and the purpose and the result are clear.

In addition, as disclosed in Patent 2, it merely describes that an illuminance sensor is arranged on the side A. As in the disclosure of the patent, all measured values immediately after opening are fully considered. It is clear that it has not been done.

Therefore, it is necessary to secure the degree of craying immediately after opening the, and to improve the crying and to provide the crying method for the spi. To solve the problem

This is an example of an example in the five states. Good for carrying out Ming

First, before entering the state of the state of clarification, explain to the point of clarification.

Is an example of a device to explain the reasoning of the device. , It includes a display that displays information related to light and a clock light 3 that controls the degree of clock light 2 of the display.

In addition, it includes a sensor 4 for detecting the ambient brightness related to the light, 5 for detecting, and 6 for correcting the degree to a predetermined degree. Further, it includes a control 7 for controlling the display, the light 3, the illuminance sensor 4, and the open / close 5 and 6 according to the light.

Then, when the control 7 detects the opening state from the opening / closing state 5, the control 6 reads a predetermined value from the memory 6, and turns on the light 2 of the display in the light 3. Then, the degree of the display light 2 is changed to the light 3 according to the degree of correction of the surrounding light detected by the sensor 4 and the degree of the light stored in the sensor 6.

In this way, the specified light 2 is turned on immediately after opening, and the degree of the right light 2 is changed according to the degree correction for the surrounding and the degree. It is possible to look up.

Below, this will be explained. First, I will explain the situation. 2 is the state of the clear. In addition, the same number is attached to the same part in and it is clarified.

As an example, according to Ming, a folding device. However, is not limited to this, and if it is a folding device, the present invention can be applied to other transfers or fixed communication devices. Referring to FIG. 4, the antenna 8, the radio unit 9, the spy and the audio 2, the audio deck 3, the production unit 0, and the display are included. In addition, the light 2, the light 3, the illuminance sensor 4, the open / close 5, and the program related to the light

4, me 6, and control 7.

7 controls the wireless unit 9, the audio deck 3, the memory 6, the program 4, the open / close 5, the illumination sensor 4, the clock light 3, the display and the working unit.

According to the control, the base communication is performed through the radio unit 9 and the antenna 8 by the control 7. The line unit 9 receives the signal at the antenna 8, selects the signal wave number, performs wave number conversion, amplifies and adjusts the signal number, and outputs 7 the received data.

7 processes the received data and inputs the audio signal to deck 3, and audio deck 3 converts the audio signal to an analog signal. And spies

Outputs audio. The audio input from Iq 2 is converted into audio deck 3 by PC (e Codeodao (aaoda)), control 7 processes the signal into transmission data, and radio section 9 modulates the transmission data. Amplified as the specified wave number and the signal is transmitted from Athena 8.

For 7, intrusion and extraction of 6, display control, extraction processing of cropping unit 0, extraction of constant values from illumination sensor 4, and extraction processing of opening and closing 5. The sensor 4 detects the ambient pitch. 5 detects the position.

If the control 7 detects that the open state is changed to the open / close state 5, the control 7 reads a predetermined value from the menu 6 and sets the numerical value to the credit 3. The credit 3 lights up the credit 2 according to the set value. Program 4 contains a program for the display lying method described later. Read the program from Program 4 and control each part. 3 and 4 are examples of positions related to Ming. Referring to FIG. 4, a foldable folding device according to Ming is shown, and a device in which the illuminance sensor 4 is mounted is shown. In 3, the illuminance sensor 4 is set to cropping 0 (in the example, the top of cropping 0), and in 4, the illuminance sensor 4 is set to the display (in, example, top of the display). Is shown.

5 is a diagram showing an example of degree correction for a predetermined degree and degree stored in 6. FIG. 5 indicates that in the given example, it will be stored in 6 brightnesses. It is referred to by control 7 when the position of this device changes from closed to open.

In addition, 5 indicates that the multiple degree measurement values and the degree correction corresponding to each degree measurement value are stored in 6 as the degree correction test. This te is referred to by control 7 after is changed from closed to open. In other words, it is a degree correction test that is referred to when control is performed according to the surroundings. In addition, it is desirable that the predetermined and degree correction test be set to a value determined in consideration of the experiment.

Next, I will explain the work of the state. 6 is a chart indicating the operation. First, when the position changes from the closed state to the open state, the opening / closing 5 notifies the control 7 (Step 5. 7 receives the notification and reads a predetermined value from the method 6 (Step S 2). Set to light 3 (step 3) Clock light 3 turns on light 2 according to the setting (step S4)

Next, the control 7 reads a constant value from the illuminance sensor 4 (step 55), and reads from the correction 6 corresponding to the constant value (step 56). Next, the control 7 adds the correction to the currently determined value, obtains the final value, and sets it to the click light 3 (step S7).

Then, the clock 3 changes the degree of the clock 2 according to the set value (step S8. Steps S5 and S8 are adjusted in accordance with the surroundings. Next, we return to 7 and explain the degree control in the light. In the light, when a change to the open state is detected, a predetermined (brightness shown in b 2) is set to the clock light 3, and the clock light 2 is turned on.

This constant (brightness shown in b2) should be determined in consideration of the display. In the embodiment, for example, the predetermined (brightness shown in b2) is larger than the (brightness shown in b) in a relatively environment (that is, bb2 )

Next, the degree adjustment according to the constant value from the illuminance sensor 4 is performed. For example, when the degree measurement value is relatively high (when compared), the luminance (

The brightness is increased toward the brightness (shown in 7). If the measured illuminance is relatively (comparative), the brightness is increased (shown in 7c) toward the brightness (brightness shown in b3).

As described above, according to the state of the art, if an open state is detected from the position of a device that has the function of adjusting the display light degree according to the surroundings, the predetermined weight By turning on 2 and changing the brightness step by step until it reaches the surrounding area, it is possible to secure the degree of crispness immediately after opening the device and to improve the brightness.

Next, I will explain in two clear states. FIG. 8 is a diagram showing a predetermined example in the clear 2 state. In the state given

(7 b 2) Do not mean.

On the other hand, in the present embodiment, as shown in 8, the user can only specify the data by the operation (and the surroundings are relatively 3, and 3). For, and for, and for "C 3) are prepared. Therefore, these fixed values correspond to this. The information is stored in 6.

As described above, according to the two states described above, it is possible to set the degree of the clock light in accordance with the use situation.

Next, explanation will be given in the following three states. 9 is a graph showing the relationship of time in the three states. In this state, the conversion from the predetermined value to the surroundings is linear (in 7C and 7d in 7), but in this embodiment the surroundings from the predetermined value as shown in 9 Control is performed so that the transition is made between the predetermined intervals according to the level. Therefore, these reports are stored in 6.

As described above, according to the third aspect, because it is a configuration that controls a certain duration, it reduces the sense of comfort even if the set value can be set relatively according to the surroundings from the predetermined value. Next, I will explain in 4th state. Is a graph showing the degree and time relationship in the four states. In this state, the case where the conversion from the specified value to the surroundings is linear (in 7C and 7 in 7) is shown, but in this embodiment, the specified value is The brightness is controlled to change in a predetermined step until it depends on the surroundings. Therefore, these step information is stored in 6.

As described above, according to the four modes described above, since the brightness is controlled, the sense of comfort is reduced even when the set value can be relatively set according to the surroundings from the predetermined value. It becomes possible. Next, I will explain in the following five states. Is an example of the case in the five states. Refer to the previous

Unlike the state, the sensor 4 of the present embodiment is mounted on the surface of the display, that is, the surface exposed to the outside in the closed state. In this way, when the illuminance sensor 4 is mounted in a place, it is possible to always detect the surrounding area. However, in a situation where the device is closed, depending on the surroundings Since the degree of spi is not adjusted, the illuminance sensor 4 is often deactivated because power is intended in this situation.

When it is detected that has changed from the closed state to the open state, the illuminance measurement value set immediately before is used in the related technique in consideration of the crisp when the is opened. The value set before the illuminance sensor.

For this reason, when the environment is relatively closed and the environment is opened, the brightness increases as the illuminance measurement value is relatively low, and there is a very bad state.

Therefore, in the present embodiment, even when the illuminance sensor 4 is mounted on the surface on the display side, when the change of the open state is detected from the same state as the above-mentioned four to four states, A predetermined clip that can be secured is turned on, and the brightness is changed step by step until it is surrounded.

As described above, according to the five states described above, when the illuminance sensor 4 is mounted on a display, that is, a surface that is exposed to the outside in a state where the is closed, the degree of clock light after the is secured. It is possible to improve.

Next, I will explain in the six states. It is also related to the six-screen Krypley program. Referring to 2, program 4 is provided in the place related to Ming. This program contains a program that shows the display order of the display shown in chart 6.

7 reads this program from program 4, and controls opening / closing 5, me 6, light 3 and sensor 4 according to the program. Since the contents have already been described, they are omitted here.

As described above, according to the six states described above, it is possible to obtain a program that can secure the degree of crying immediately after opening and can move up. It is.

Although the present invention has been specifically described above based on the embodiment, the invention is not limited to the above-described embodiment, and modifications can be made without departing from the scope of the invention. These are also included in the present application. This is no problem.

The application is based on the home country 2 08 72858 and is incorporated herein in its entirety.
